Description

Technical Field

[0001] The invention relates to the technical field of piston processing, and in particular to a rapid positioning device for piston processing. Background Art

[0002] The piston is a reciprocating component in the cylinder block of a car engine. As the requirements of automobiles for engine power, economy, environmental protection and reliability become increasingly stringent, the piston has developed into a high-tech product that integrates a number of new technologies such as lightweight and high-strength new materials, special-shaped outer cylindrical composite surfaces, and special-shaped pin holes. In order to ensure the heat resistance, wear resistance, smooth guiding and good sealing function of the piston, a special positioning device is required to position the piston during the piston processing process.

[0003] In the prior art, the utility model of Chinese patent application No. 202123198324.5 discloses a rapid positioning device for automobile piston processing, which specifically relates to the technical field of automobile piston processing equipment. When the existing rapid positioning device for automobile piston processing is in use, the positioning block may cause collision damage to the piston due to excessive movement speed when positioning the piston, affecting the processing effect of the piston, and has certain limitations, including an installation frame, a bottom plate is provided at the bottom of the installation frame, and fixed frames are symmetrically provided on both sides of the installation frame. A cylinder is provided inside the fixed frame, and the output end of the cylinder extends to the inside of the installation frame. A positioning block is provided at the output end of the cylinder, and a protective component is provided on the top of the positioning block, and a functional component is provided inside the bottom plate. The protective component designed in the utility model is convenient for protecting the end surface of the positioning block, and is also convenient for avoiding collision damage between the positioning block and the piston, and has high practicality.

[0004] However, the above technical solution cannot realize the flipping adjustment of the piston after the piston is clamped and positioned. When other surfaces of the piston need to be processed, the clamping and positioning must be released first, and then turned over and re-clamped. The operation process is cumbersome and greatly reduces the processing efficiency. In addition, the debris generated during the processing of the piston may pass over the mounting frame. The mounting frame has limited effect on collecting waste and it is difficult to completely block the debris, thereby reducing the collection effect of the processing debris. For this reason, we propose a piston processing rapid positioning device to solve the above problems. Summary of the invention

By providing the slope 4 at the top of the collection box 3, it is convenient to collect the debris generated during the piston processing and facilitate the debris to fall into the collection box 3.

[0052] In this embodiment, a rubber pad 11 is fixedly bonded to one side of the two clamping plates 10 that are close to each other.

[0054] In this embodiment, sliding grooves 13 are provided on the top inner wall and the bottom inner wall of the mechanical box 5, and the top and bottom ends of the fixed rod 12 are slidingly connected to the two sliding grooves 13 respectively.

By providing the third spring 27, the clamping rod 26 can be driven to move upward and reset.

[0058] Working principle: When in use, first connect the electric push rod 6 and the drive motor 14 to an external power supply, then place the piston to be processed inside the mounting frame 1 and between the two clamping plates 10, and then start the two electric push rods 6. At this time, the two electric push rods 6 can drive the two connecting rods 7 to approach each other. When the two connecting rods 7 approach each other, they can drive the two moving rods 9 to approach each other. When the two moving rods 9 approach each other, they can drive the two clamping plates 10 to approach each other and clamp and fix the piston. At this time, the rapid positioning of the piston is achieved. When the piston is fixed, the processing head of the processing equipment is inserted into the interior of the installation frame 1, and then the two rectangular tubes 17 are pushed toward each other, so that the two rectangular plates 18 can be driven to approach each other and contact the processing equipment, and the top outlet of the installation frame 1 can be blocked. At the same time, when the rectangular tube 17 moves, the vertical rod 20, the sliding ring 21 and the block 23 can be driven to move toward the installation frame 1. When the block 23 moves and contacts the card rod 26, the card rod 26 can be squeezed to move downward. At this time, when the block 23 moves to the card rod 2 6, the elastic reset characteristic of the third spring 27 can drive the clamping rod 26 to move upward and complete the clamping installation with the clamping block 23. The clamping limit cooperation between the clamping block 23 and the clamping rod 26 can fix the positions of the rectangular tube 17 and the rectangular plate 18 to ensure the stability of the rectangular tube 17 and the rectangular plate 18 when blocking the bottom end of the installation frame 1. In this way, the piston processing debris can be blocked to prevent the debris from splashing out of the installation frame 1, and the rectangular tube 17 and the rectangular plate 18 are elastic, so as not to cause damage to the processing equipment. The preparation extends into the installation frame 1 to process the piston, causing no obstruction, which can facilitate the processing equipment to move forward, backward, left and right. In addition, by starting the drive motor 14, the first gear 15 can be driven to rotate. When the first gear 15 rotates, it can drive the second gear 16 and the moving rod 9 to rotate. When the moving rod 9 rotates, it can drive the clamping plate 10 and the piston to rotate. At this time, the piston is changed. In this way, there is no need to re-clamp the piston for changing the surface, which is convenient for multiple surface processing of the piston, thereby improving processing efficiency and having strong practicality.
